Arduino tutorial (Part 13, joystick), 2nd edition
This is the post’s second edition. It’s shown one more project to control servomotors with a joystick, using another method.
Remote control vehicle
This is a project of a vehicle with tracks controlled by a pair of RF modules and intergated circuits HT-12E (encoder) and HT-12D (decoder).
How to control a robotic arm without a microcontroller?
It is possible to control a robotic arm without a microcontroller, using simple electronic circuits. This post shows how.
Seebeck and Peltier effects
The Seebeck and Peltier effects are thermoelectric phenomena that explain the operation of thermocouples, temperature sensors with 2 different materials.
Star and delta configurations
In addition to parallel and series, impedances also can make star and delta connections. Also are shown the transformations.
How to polarize BJT transistor? (Part 3)
This is the third and last part of the series about BJT transistor polarization. Other circuit configurations are shown.
Capacitance and inductance: More information
I received requests to write more about capacitance and inductance. This post can be considered as the second part of derivated electrical quantities.
How to polarize BJT transistor? (Part 2)
This is the second part about BJT polarization. Are shown projects of circuits with fixed and emitter’s stable polarization.
Technical Museum Nikola Tesla (Part 4)
This is the last part of Technical Museum Nikola Tesla.
